While we don't recommend tight connections while traveling (especially in Seattle), sometimes it can't be helped. If you need to arrive in Juneau around 3:30 PM and want to catch the 4:00 PM seaplane flight to Pelican it is possible but we make sure to inform Alaska Seaplanes ahead of time and keep them apprised of the situation so that they know you will be showing up for the flight even though you are not there to check in an hour prior.
